Functions
int	mpi_gstbmm (double **V, int nrow, int m, int m_rowwise, Block *tpltzblocks, int nb_blocks_local, int nb_blocks_all, int id0p, int local_V_size, int64_t *id0gap, int *lgap, int ngap, Flag flag_stgy, MPI_Comm comm)
	Performs the multiplication of a symmetric, Toeplitz block-diagonal matrix, T, by an arbitrary matrix, V, distributed over processes in the generalized column-wise way. This matrix V contains defined gaps which represents the useless data for the comutation. The gaps indexes are defined in the global time space as the generized toeplitz matrix, meaning the row dimension. Each of his diagonal blocks is a symmetric, band-diagonal Toeplitz matrix, which can be different for each block.
int	reset_gaps (double **V, int id0, int local_V_size, int m, int nrow, int m_rowwise, int64_t *id0gap, int *lgap, int ngap)
	Set the data to zeros at the gaps location.
int	build_gappy_blocks (int nrow, int m, Block *tpltzblocks, int nb_blocks_local, int nb_blocks_all, int64_t *id0gap, int *lgap, int ngap, Block *tpltzblocks_gappy, int *nb_blocks_gappy_final, int flag_param_distmin_fixed)
	Build the gappy Toeplitz block structure to optimise the product computation at gaps location.
